Enviro-Brick pressed sawdust fireplace fuel, is an effective alternative to other fuels such as fuel oil and coal. Unlike coal and other fossil fuels that extract CO2 from the ground and deposit it into the atmosphere when burnt, Enviro-Bricks are made from sawdust and are considered CO2 neutral because the trees they are manufactured from extract more CO2 from the atmosphere than the logs emit when burnt for heat. As a matter of fact, Enviro-Bricks produce 52% less particulate matter to the atmosphere than cordwood.

Enviro-Bricks are twice the density of cordwood and about the same energy density as coal with burn times significantly longer than cordwood.
